Generation time of strains in competition in axenic media.

<p>The italicized values are the median generation times of the drug susceptible strains in the presence of the respective drug resistant strains. The values formatted as bold are the mean generation times of the drug resistant strain in the presence of the respective drug susceptible strain. The data has been represented as mean ± SD from 3 independent experiments. The values have been used to plot <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033507#pone-0033507-g003" target="_blank">Figure 3</a>.</p><p>Generation time is calculated using the formula:</p><p></p><i>t</i> = total time; <i>n</i> = no of generations.<p></p><i>Nt</i> = Number of viable cells at final time t; <i>N0</i> = Number of viable cells at time 0.<p>
